What gender do you think my EEs are?

My three EEs are about four weeks old. I'm afraid I may have at least one rooster. Chestnut seems to be dominate and is the biggest (by at least an ounce compared to Cique). Its comb just started showing a few days ago. Chestnut likes to come over to me to be pet or held. Nutmeg is taking a LOT longer to feather out. She is just getting a few tiny tail feathers and is about 1.5-2 ounces (three days ago) lighter than Chestnut. She likes to hide under the others. Cique isn't as friendly and has the cheek tufts as does Chestnut but Nutmeg does not.
